But the occurrence of IPEH in breast is rarely reported in literature. We diagnosed this case in a 2 month old child presented with right breast bud swelling. On histopathology diagnosed as IPEH/ Masson’s hemangioma. The aim of this case report to highlight the important role of clinical suspicious of such rare entities and histopathological diagnosis to avoid unnecessary aggressive line of treatment for better management of patient care.
